Creep processes in magnesium metal matrix composites
Original language description
This paper reviews the creep characteristics of the two magnesium monolithic alloys and their various discontinuous composites. It was found that both of the short-fibre reinforced AZ91 and QE22 composites exhibit better creep resistance than their monolithic alloys due to an effective load transfer in which part of the external load within the matrix is transferred to the reinforcement. Indirect composite strengthening may be caused by microstructural effects leading to a threshold stress increases thecreep resistance. However, indirect reinforcement effect can also produce weakening as it was found in the case of particle-reinforced QE22+SiC composite due to enhanced precipitation of Nd-rich phases at the SiC/matrix interfaces. Comparison between AZ91 and QE22 magnesium hybrid composites reinforced with short carbon fibre and SiC particulates has shown, that the creep resistance of the hybrid reinforced AZ91 alloy was considerably improved by comparison with the unreinforced matrix
